  Todo, bugs to fix:


  - delay.show = 400 , delay.hide = 400


    go Product Three -> Live Demo -> Test Drive -> Test Three , go fast to Product Four.


    Result: 2 elements highlighted in the same section


  - delay.show = 0 , delay.hide = 400


    go Product Three -> Live Demo , section out , section over, seciont out.


    Result: Live Demo is not highlighted


  - active className changing, unnecessary blink


  - opera: hideSection() exceptions are throwed
